q The common rail fuel injection system (CRI)
consists of more precise parts than the parts
used in the conventional fuel injection pump
and nozzle. If foreign material enters this sys-
tem, it may cause a failure. Use special care to
prevent entry of the foreign material when ser-
vicing the fuel system.
Use care for working environment
q Avoid filter change or repairing the machine in
rain or high winds, or at places where there is a
lot of dust.
Sealing openings
Plug the pipes and the openings of the compo-
q
nents which are removed with the caps, tapes,
vinyl bags, etc. to prevent foreign material from
entering. Never perform repair works under the
condition that the openings are left as they are
or plugged with cloths as foreign material may
enter or environment may be polluted by the oil
leaked. Do not discard the waste oil some-
where or other. Hand it over to your customer
for disposal, or dispose it by yourself.
How to clean parts when dirt is stuck .
q If any dirt or dust sticks the parts of the fuel
system, clean it off thoroughly with clean fuel.
Precautions for replacing fuel filter cartridge
q Be sure to use the Komatsu genuine fuel filter
cartridge.
The common rail fuel injection system (CRI)
q
consists of more precise parts than the parts
used in the conventional fuel injection pump
and nozzle. In order to prevent foreign material
from entering this system, the filter employs a
specially high performance of filter element. If
a filter element other than the genuine one is
used, the fuel system may have a failure.
Accordingly, never use such a filter element.
